Applied rabbit anti-5-HT and mouse monoclonal anti-TPH antisera, the localization of 5-HT and its synthesizing enzyme TPH in the visual system, midbrain, and suboesophageal ganglion of the beetle Harmonia axyridis (Coleoptera: Coccinellidae) was studied by Streptavidin-Peroxidase immunohistochemical method on Colophony-Paraffin embedded serial sections.

运用树脂石蜡组织包埋切片技术，结合免疫组化链霉菌抗生物素蛋白-过氧化物酶双染法，采用兔抗5-HT抗血清和鼠抗TPH单克隆抗体，初步构建了异色瓢虫Harmonia axyridis视觉系统、脑中部及咽下神经节5-HT及其合成酶TPH抗原系统的免疫组织化学反应模式。

Applied rabbit anti-5-HT and mouse monoclonal anti-TPH antisera, the localization of5-HT and its synthesizing enzyme TPH in the visual system, midbrain, and suboesophagealganglion of the beetle Harmonia axyridis (Coleoptera: Coccinellidae) was studied byStreptavidin-Peroxidase immunohistochemical method on Colophony-Paraffin embeddedserial sections. An overall observation reveals that the brain structure of the beetle is relativelydistinct.

After varied survival periods, the model mice were sacrificed to get the specimens of SN fixed, embedded and coronally sectioned continuously. The microsections were processed by immunohistochemistry to label the DA neurons and Calbindin D28k-containing neurons with the antibodies against tyrosine hydroxylase and CR respectively. The labeled cells were counted under microscope and analyzed statistically.

模型动物存活1周后，一部分取其中脑黑质节段，固定、包埋做连续冠状石蜡切片，以免疫组织化学染色方法，显示各组酪氨酸经化酶和钙结合蛋白表达阳性细胞，光镜观察并细胞计数，统计学分析；另一部分取其中脑黑质组织匀浆，行TH、CB的Westem blot免疫印迹方法检测，用LabWorks软件分析处理。

The structure, division and growth of embryogenic callus of litchi and longan were observed by paraffin method.

通过石蜡切片观察荔枝胚性愈伤组织的结构以及分裂、生长的方式，并与龙眼胚性愈伤组织作比较。

The salty gland of Messerschmidia sibirica is developed from epidermic cell of stem and leaf.

利用石蜡切片法研究了砂引草茎叶的解剖结构，尤其是对泌盐腺的位置、泌盐腺的形态结构及泌盐腺的发生发育过程进行了系统的研究，结果表明：砂引草茎的初生结构维管束是外韧的，且其有10-12束，大小不等，髓和髓射线发达；叶的上下表皮细胞各一层，栅栏组织与海绵组织分化明显。

Activation of NF-κB(p65) with evident nuclear translocation was found in neonatal rat NEC model. The pathological lesions indicated that intestinal tissue necrosis in varying degrees in group C and D, which were 2-4 points, but obviously lessened in group E, which were 0-2 points. Conclusions Intestinal inflammation is ameliorated after the ITF is injected hypodermically.

结果 C、D组组织中NF-κB(p65)阳性表达较A、B及E组显著升高P(下标 a.01，E组与A、B组比较也有升高P(下标 a.01，且随NF-κB(p65)的激活有明显的核转移；病理切片示C、D组HE染色见肠壁损伤轻重不一，可见全肠黏膜绒毛坏死，病理评分2~4分；E组轻度肠上皮细胞脱落，顶端绒毛坏死，肠组织病理评分0~2分。

Under imitated daily field microclimatic conditions for heat stress, the rice cultivar "Jinyou63"(which is a hybrid rice combination) was treated with a consecutive 3-day heat stress during meiosis in phytotron. Anther and pollen tissues at different development stages after subjected to heat stress were sampled and analyzed for transverse abnormalities.

本研究模拟田间典型灾害天气条件，在人工气候箱内对杂交水稻&金优63&花粉母细胞减数分裂期进行连续3 d的热害胁迫处理，对处理后不同发育时期的花药组织取样切片观察，从组织、细胞水平探讨水稻受高温胁迫后花药可能出现的早期异常特征。

In HE staining, the experimental group showed the histopathology of OB; the transplanted tracheas were obliterative, inflammatory cell infiltrated, tracheal epithelium completely shed, and fibroblasts predominantly proliferated. While in the control group, there was no apparent histological change in normal trachea.

苏木精－伊红染色病理切片示实验组小鼠移植气管管腔闭塞，慢性炎细胞浸润广泛，气管上皮完全脱落，纤维组织增生明显，呈现闭塞性细支气管炎表现：对照组小鼠移植气管的组织形态未见明显异常。

However, the incidence of carrying mtDNA4977 deletions in heart and liver were no significant difference between presbycusis patients and the control group.

老年聋患者颞骨切片和蜗核组织中mtDNA4977缺失的发生率明显高于老年听力正常组，其差异具有显著性意义（χ2检验，P＜0.05）；而与听觉无关的心肌和肝脏组织中mtDNA4977缺失发生率在两组之间差异无显著性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
